Editing Software versioning (section)

===Dropping the most significant element===
Sun's [[Java (programming language)|Java]] has at times had a hybrid system, where the internal version number has always been 1.''x'' but has been marketed by reference only to the ''x'':
* JDK 1.0.3
* JDK 1.1.2 through 1.1.8
* J2SE 1.2.0 ("Java 2") through 1.4.2
* Java 1.5.0, 1.6.0, 1.7.0, 1.8.0 ("Java 5, 6, 7, 8")

Sun also dropped the first digit for Solaris, where Solaris 2.8 (or 2.9) is referred to as Solaris 8 (or 9) in marketing materials.

A similar jump took place with the [[Asterisk (PBX)|Asterisk]] open-source PBX construction kit in the early 2010s, whose project leads announced that the current version 1.8.x would soon be followed by version 10.<ref>{{cite web|author=Kevin P.

This approach, panned by many because it breaks the semantic significance of the sections of the version number, has been adopted by an increasing number of vendors including [[Mozilla]] (for [[Firefox]]).
